core/pcie-slot: Don't bail early in the power on case

Exiting early in the power off case makes sense since we can't disable
slot power (or assert PERST) for suprise hotplug slots. However, we
should not exit early in the power-on case since it's possible slot
power may have been disabled (or just not enabled at boot time).
